For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] The invention discloses a multilayer shear microfluid reactor.

[0040] Reference Figures 1 to 3 , Figures 8 to 14 , a multilayer shear microfluidic reactor, comprising a connecting shaft 1, on which a plurality of reaction components are arranged. The reaction components include a rotor reaction piece 2 and a stator reaction piece 3, the rotor reaction piece 2 is arranged in contact with the surface of the connecting shaft 1 and connected to the connecting shaft 1, and the rotor reaction piece 2 and the connecting shaft 1 can be connected by a key connection or a bolt connection, as long as the rotor reaction piece 2 can rotate with the connecting shaft 1. A rotor support sleeve 4 is arranged between adjacent rotor reaction pieces 2, and the rotor support sleeve 4 is convenient for controlling the distance between adjacent rotors. There are reaction holes on the stator reaction piece 3, the rotor support sleeve 4 is located in the reaction hole, and a first circulation area 31 is arranged between the inner wall of the reaction hole and the outer surface of the rotor support sleeve 4. A first reaction tooth group 21 is arranged on the rotor reaction piece 2, and a second reaction tooth group 34 is arranged on the stator reaction piece 3, the first reaction tooth group 21 is located in the second reaction tooth group 34, and a second circulation area 32 is arranged between the first reaction tooth group 21 and the rotor support sleeve 4, and a jacket 5 is arranged outside the rotor reaction piece 2, and a third circulation area 33 is arranged between the jacket 5 and the second reaction tooth group 34. During operation, the material passes through the first circulation area 31 , the second circulation area 32 and the third circulation area 33 of each reaction assembly in sequence. The material needs to pass through the first reaction tooth group 21 and the second reaction tooth group 34 to reach the third circulation area 33 from the second circulation area 32 .

[0041] The connecting shaft 1 is connected to the rotor reaction piece 2, so that the connecting shaft 1 can drive the rotor reaction piece 2 to rotate. When the material passes through the first reaction tooth group 21 and the second reaction tooth group 34, it is crushed and stirred by the rotating first reaction tooth group 21, thereby improving the reaction efficiency of the material. The material passes through the first flow area 31, the second flow area 32 and the third flow area 33 of each group of reaction components in turn to achieve a stirring cycle, and then the reaction effect can be controlled by controlling the number of reaction components to adapt to different materials. At the same time, the material can complete the reaction and be discharged by passing through multiple groups of reaction components in turn, and the reaction efficiency is relatively high.

[0042] Specifically, the first reaction tooth group 21 includes a plurality of first crushing teeth 211, and a plurality of the first crushing teeth 211 are arranged along the circumferential array of the rotor reaction piece 2, and a first shunt gap 212 is provided between adjacent first crushing teeth 211; the second reaction tooth group 34 includes a plurality of second crushing teeth 341, and a plurality of the second crushing teeth 341 are arranged along the circumferential array of the stator reaction piece 3, and a second shunt gap 342 is provided between adjacent second crushing teeth 341. When the material passes through the second reaction tooth group 34 and the first reaction tooth group 21, it is first dispersed by the second shunt gap 342, and then enters the first shunt gap 212 under the impact of the first crushing teeth 211, and then passes through the first shunt gap 212 and converges into the third flow area 33, and the reaction effect is improved in the continuous dispersion, impact, and mixing cycle process, and this method can make the material react as completely as possible.

[0043] In another embodiment, referring to Figure 4 and Figure 5 The first reaction tooth set 21 may be provided with two sets, the two sets of first reaction tooth sets 21 are arranged along the radial direction of the rotor reaction member 2 , and the second reaction tooth set 34 is located between the two sets of first reaction tooth sets 21 .

[0044] In another embodiment, referring to Figure 6 and Figure 7 The second reaction tooth set 34 may be provided with two sets, the two sets of second reaction tooth sets 34 are arranged along the radial direction of the stator reaction member 3 , and the first reaction tooth set 21 is located between the two sets of second reaction tooth sets 34 .

[0045] In other embodiments, more groups of the first reaction tooth groups 21 and the second reaction tooth groups 34 may be provided, and the more groups of the first reaction tooth groups 21 and the second reaction tooth groups 34 there are, the better the reaction effect of the material will be.

[0046] The jacket 5 is located between adjacent stator reaction pieces 3, and the stator reaction piece 3 is provided with a jacket 5 fixing groove 35 for inserting the jacket 5 so as to limit and seal the jacket 5. A first heat exchange cavity 51 is provided in the jacket 5, and a first heat exchange inlet 52 and a first heat exchange outlet 53 communicating with the first heat exchange cavity 51 are provided on the jacket 5. A second heat exchange cavity 37 is provided in the stator reaction piece 3, and a second heat exchange inlet 371 and a second heat exchange outlet 372 communicating with the second heat exchange cavity 37 are provided on the stator reaction piece 3. The first heat exchange cavity 51 and the second heat exchange cavity 37 facilitate the introduction of cooling medium so as to control the temperature of the material.

[0047] In addition, a temperature measuring component 36 is provided on one of the stator reaction parts 3, and the temperature measuring component 36 is connected to the inner hole of the stator reaction part 3, and is used to monitor the temperature of the first flow area 31. The stator reaction part 3 with the temperature measuring component 36 can be installed in the middle position of the entire reactor, or can be installed at the feed position and the discharge position of the reactor. The temperature measuring component 36 can be a temperature sensor.

[0048] One end of the multiple reaction components is provided with a feed flange 6, and the other end is provided with a discharge heat exchange jacket 7. The feed flange 6 is provided with a feed port 61, which is connected to the first flow area 31 of one group of reaction components; the discharge heat exchange jacket 7 is provided with a discharge pipe, which is connected to the third flow area 33 of one group of reaction components, so as to realize the entry and outflow of materials. The discharge heat exchange jacket 7 is also provided with a heat exchange cavity, a heat exchange inlet and a heat exchange outlet.

[0049] It should be noted that the connecting shaft 1 does not extend to the stator reaction member 3 close to the feed flange 6, that is, the first flow area 31 of the stator reaction member 3 is the entire inner hole thereof, so that the material can enter.

[0050] The discharge heat exchange jacket 7 is fixedly connected to a base flange 8, and a sealing assembly 81 is installed on the base flange 8 to facilitate sealing the end of the discharge heat exchange jacket 7 away from the reaction assembly. The feed flange 6, the discharge heat exchange jacket 7 and multiple groups of reaction assemblies are penetrated by a group of fastening bolts 9 and fixed by the fastening bolts 9 to realize the assembly of the reactor.

[0051] Working principle: The connecting shaft 1 is connected to the rotor reaction part 2, so that the connecting shaft 1 can drive the rotor reaction part 2 to rotate. When the material passes through the first reaction tooth group 21 and the second reaction tooth group 34, it is crushed and stirred by the rotating first reaction tooth group 21, thereby improving the reaction efficiency of the material. The material passes through the first circulation area 31, the second circulation area 32 and the third circulation area 33 of each group of reaction components in turn to achieve a stirring cycle, and then the reaction effect can be controlled by controlling the number of reaction components to adapt to different materials. At the same time, the material can complete the reaction and be discharged by passing through multiple groups of reaction components in turn, and the reaction efficiency is relatively high. The setting of the first heat exchange chamber 51 and the second heat exchange chamber 37 facilitates the control of the temperature during the material reaction process to further improve the reaction efficiency and ensure the reaction effect.

[0052] In addition, the overall volume of this solution is smaller, and the space occupied by the factory is smaller. At the same time, multiple connecting shafts 1 can be connected through a transmission mechanism to achieve synchronous transmission, thereby improving the reaction efficiency.

[0053] The materials in this solution react in a relatively small space, and the reaction is more complete, so the reaction effect far exceeds that of traditional reaction tanks.

[0054] The rotor support sleeve 4 controls the distance between adjacent rotors and also ensures that there is a gap between the end of the rotor reaction element 2 away from the first reaction tooth set 21 and the stator reaction element 3, so as to facilitate the flow of materials between adjacent reaction components.

[0055] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
